Is TBB undervalued?

At 18.26 (close of 16 Oct 2026), TBB trades 75% below the GLS average fair value of 73.41. That average comes from 9 models run on the latest filings, and 8 of them land above the current price. Margins of safety over 30% are the exception rather than the rule across the ~7,400 stocks we value each night, so the number earns AT&T Inc. 5.35% GLB NTS 66 the full Value points in the Wheel Score - and a closer look at what the market is pricing in.

The 9 models disagree widely: DDM gives 16.33 while DCF gives 192.71. A spread that wide means the average is sensitive to which methods you trust; the model table below shows where each one lands, and the Quote page lets you switch any of them off.

The nightly engine files TBB under High Yield Income: a dividend yield above 4%.

Quality and financial health

On financial health TBB scores 7/9 (Piotroski): most of the nine tests - positive earnings and cash flow, falling debt, rising margins and turnover - are passed, which is the kind of balance sheet a wheel trader is happy to be assigned. The GLS Moat score is low at 4.3 out of 10, which says the ten-year record of revenue, earnings, margins and returns on capital has been inconsistent - growth and shocks rather than steady compounding.

Returns on capital are moderate - ROIC 7.7%, ROE 19.8%, ROA 5.2% - with debt at 1.57 times equity and a free-cash-flow yield of 11.2%.

The dividend yield is high at 4.81% (payout ratio 37%). A yield this size is often the market's way of pricing a risk to the payout, so the health score and cash flow matter more than usual. Revenue comes mainly from Wireless service 58%, Equipment 18%, Advanced home internet 9% (quarter Q2 FY2026).

Institutional ownership scores 1/10, insider activity 5/10 and Congressional trading 5/10 on the GLS smart-money scales.

Wheel Score 39: No options

TBB has no listed options in the nightly snapshot, so there is nothing to sell and the stock cannot be wheeled however good the business; the Wheel Score is capped at 39 and shown as "No options" (39 here). The valuation and quality numbers still apply to owning the shares outright.

Volume runs at 166k shares a day on a market cap of $158.2B, with a beta of 0.37 - a low beta, so day-to-day moves are smaller than the market's; the Stability part of the Wheel Score gives that 13 of 20.

The Wheel Score ranks ~7,400 US stocks for selling cash-secured puts and covered calls; it is updated nightly and is not a recommendation. The walkthrough lesson shows how the score fits into a trade, start to finish.

Upcoming events

AT&T Inc. 5.35% GLB NTS 66 reports earnings on 28 Oct 2026 (before the open) - inside the 14-day window the Sunday Scan avoids, because a put sold now would carry the report's gap risk. The shares go ex-dividend on 16 Oct 2026 (0.3344 per share), so a covered call sold before then carries a small early-assignment risk around that date.
